SPECIFICATION formingpart of Letters Patent No. 730,921, dated June 16,1903.

Application filed May 10, 1902. Serial No. 1061800. F m l- To all whom,it may concern.-

Be it known that I, HERMANN J OEsT, m anufacturer, a subject of theGerman Emperor,

and a resident of Hanover, in the Empire of Germany, have inventedcertain new and useful Improvements in the Manufacture of Table-Knives,Forks, or Similar Articles, of which the following is a full, clear, andexact description.

This invention relates to improvements in the manufacture oftable-knives, forks, and similar articles; and the object is to connectthe tang throughout its entire length, or nearly so, with the handle andat thesame time anchor it in the same, so as to protect both tang andhandle against the entrance of liquid and render them immune to theeffects of acid liquids or vapors. This object is completely attained bycasting around the tang of the knife or fork or other like implement ina suitable mold an alloy of aluminium and magnesium, (magnalium) Thisalloy closely adheres to iron or steel, behaving toward the latter likea solder, so that the iron or steel tang becomes a part of the handle.

The annexed drawings illustrate two forms of the invention inconnectionwith a table knife.

Figure 1 is an elevation of the knife with the handle in section; Fig.2, a section of Fig. 1 on the line A B, and Fig. 3 another form of theknife with another form of tang.

Around the suitably-fashioned tang a, of iron or steel, which extendspractically through the entire lengthofthehandle, an alloyof aluminiumand magnesium (magnalium) is cast in a mold corresponding in size andshape to the handle in such a manner that the casting b, whichintimately combines to an integralwhole with the tang a, itself formsthe handle, the latter therefore requiring no. further covering orinclosure. The shape of the tang is so chosen as to produce the bestpossible anchoring with the metal cast around it. Cast handles ofmagnalium produced in this manner, which can only be removed by forcefrom the tangs, are very convenient, absolutely acid=proof, do notoxidize, and can be plated with silver or other metal withoutdifficulty.

When the article provided with the handle becomes useless, the metalcast around the tang can be easily removed by melting and used again.

When the handle described is used for table-knives, the butt 0 of theblade is preferably cast in as well in the manner shown in the drawings,the connection of the handle with the blade being thus strengthened, theappearance of the knife improved, and the entrance of liquid between thetang and the handle rendered impossible.

WVhat I claim, and desire to secure by Letters Patent, is-

1. A table-knife or other similar article pro- ,vided witha handle ofaluminium-magnesium alloy cast around the iron or steel tang and buttand thus united with the same, substantially as described.

2. A table-knife or similar article provided with a handle ofaluminium-magnesium alloy anchored to and united with the iron or steeltang throughout its Whole length by casting, substantially as described.

3. Atable-knife or similar article having an iron or steel tang providedwith projections, and a handle form ed by an alloy of aluminium andmagnesium (magnalium) cast around said tang and having interlockingengagement with the projections thereof.

In testimonywhereof I have signed myname to this specification in thepresence of two sub= scribing witnesses.
